'ISS EarthKAM (Earth Knowledge Acquired by Middle school students) is a NASA education program which enables students, teachers and the public to learn about Earth from the unique perspective of space.'

EarthKAM is the coolest collaborate project I have ever seen for students 2-12.

In EarthKAM students actually take pictures of the Earth using a camera mounted on the International Space Station.

EarthKAM is so special it needs a wiki all it's own.

Here is my wiki which I use to teach the project to my students, they also post their work there. You can see there is a special Teacher Resources page containing most of the ppt, word doc, etc. I have made for teachers to take and use for their own.
